Answer:
cos-1(6.9/12)
sin-1( 9.8/12)
tan-1(9.8/6.9).
Step-by-step explanation:
cos <BAC = adjacent / hypotenuse
= 6.9 / 12.
sin < BAC = opposite / hypotenuse = 9.8/12
tan < BAC = opposite/adjacent = 9.8/6.9
X^5 & x^5. both of the answers are the same even though the expressions were different at the start. the results relate to the addition property from multiplication (with a negative number) and the subtraction property (with positives) from division.

Answer:
2.71 feet
Step-by-step explanation:
An architect believes that kitchens should be 2.25 times as long as they are wide.
This means
Width of kitchen = 2.25 × Length of the Kitchen
W = 2.25L
L = W/2.25
We are asked: how long a kitchen should be if it is 6.1 feet wide.
We have the proportion
L = W/2.25
W = 6.1
L = 6.1/2.25
L = 2.7111111111 feet
Therefore, the length of a kitchen = 2.71 feet when the kitchen is 6.1 feet wide.
